T0 ALL WHOM IT MAY CONGERN:

Be it known thatxwe, J. E. WIGGIN and DANIEL CROSBY, both of Stonehani, in the county of Middlesex, and State of Massachusetts, have invented an Improved Centre for Heel-Shaving Machine Guard; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Nature.

The nature of our invention `consists in the application of the ball-andvsocket joint to the guard of heel-A shavingvmachines.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction. and use.

Drawings.

Figure l is an elevation showing the guard A, and centre B, as it appears when working.

Figure 2 is an elevation showing the guard A attached to the heel of the shoe.

Figure 3 represents the centre.

Figure 4 represents a plan of the heel-guard and centro B.

Figure 5 is a section through the middle ofthe guard and centre. l

The guard A is made of any suitable metal, and in general of the shape represented in thc drawings, which agree in form with those used in connection with the heel-cutting machine patented by O. Gr. Gritchett, June 21, 1864. B represents a ccntreg the form ot' this centre is shown in section in rig. 5." Upon the end or" this centre the hall C is attached by the washer D, which is riveted firmly to the centre g the ball C is free to revolve independently of the other part of the centre. 4

The use ofour invention is obvious, as it takes the place of the centre in common use for this purpose. The advantage is this: the shoe is always kept in the proper relative position, so that the heel may be trimmed rapidly` with great precision and ease. I

What We claim as our invention, and desire to secure by Letters Patent of the United States, is-

l. The combination nud'arrangement of the guard A and pin B, when the two are constructed substantially in the manner described.

2. We clniimthe device of the ball-and-socliet joint, when combined with the guard and centre of a heeltrimming machine.
